I like this game a lot! The tactics system feels novel to me, especially with so much emphasis on turn order, both with moving and firing. Unfortunately, I haven't been able to complete the game because it crashes on me after winning the "heartless" mission. It happened both in the browser and in the downloaded version.
Thank you so much for playing! I'm so sorry that you ran into a crash. If it's not too much trouble, could you send your Campaign.txt (save) file to theallknowingalgorithm@gmail.com? It should be located under User/AppData/Roaming/Godot/app_userdata/Tactics. I'll try to push out a fix as quick as I can!
